Siwingan or woodland false buttonweed (Spermacoce remota) is a plant species in the Rubiaceae, an upright or spreading perennial herb up to 50 cm high, rectangular stems with scaly hairs on the ridges, branched and green in color.
S. remote has leaf blades up to 8 cm long, up to 2 cm wide and hairy. 5-6 lateral veins on each side of the midrib. Bare surface, undersurface with a few hairs along the veins. Stipules interpetiolar, hairy, margin scalloped with 7 teeth or pegs and teeth about 2-4 mm long.
Inflorescence in dense axillary fascicles. Individual flowers are about 5 mm in diameter. The calyx lobes are 0.5-1 mm long and are covered with hair. The corolla tube is about 2.5 mm long, the lobes 2–2.5 mm long and are covered with hairs only on the outer surface near the apex. The anthers are 1 mm long. The filaments are 1-1.5 mm long and are attached to the corolla tube.
This species grows near sea level to an elevation of 900 meters. It grows in disturbed areas and along paths and roads, rainforests, mahogany forests, teak forests, riparian forests and most of the Pantropical countries.
